Bessacarr e560 fridge

Hi
Anybody had problems with e560 thetford m180 fridge?
Brownhills have so far had 3 attempts at fixing it (4 this morning ..they don't know yet!!!!!!!!!!!!!)
If you press the increase refridge button or anywhere on the panel near it, the fridge switches off or resets. Sometimes does it randomly.
Trouble is I'm off to france on Monday carrying baby food for my daughter's baby and cannot risk it being at unsafe temperatures!

We took delivery of a new E560 earlier this year and have had the power card replaced under warranty. The auto changeover would not power the fridge with the engine running so a new, manual, card was fitted and problem cured.
